We describe herein the design, synthesis and pharmacological evaluation of novel 3-arylamine-imidazo[1,2-a]pyridine derivatives structurally designed as novel symbiotic prototypes presenting analgesic and anti-inflammatory properties. The derivatives obtained were submitted to in vivo assays of nociception, hyperalgesia and inflammation, and to in vitro assays of human PGHS-2 inhibition. These assays
我们在这里描述了新型3-芳基胺-咪唑并[1,2- a ]吡啶衍生物的设计,合成和药理学评价,其结构设计为具有镇痛和抗炎特性的新型共生原型。将获得的衍生物进行伤害感受,痛觉过敏和炎症的体内测定,以及对人PGHS-2抑制作用的体外测定。这些测定允许鉴定化合物LASSBio-1135(3a)作为抗炎和止痛共生原型。该化合物抑制适度人PGHS-2的酶活性(IC 50 = 18.5μM)和收归辣椒素诱导的热痛觉过敏(100微摩尔/ kg,口服)类似p38蛋白抑制剂SB-203580(2)。另外,关于减少角叉菜胶诱导的大鼠爪水肿(100μmol/ kg,33%的抑制作用),LASSBio-1135(3a)表现出与塞来昔布(1)相似的活性。我们还发现了衍生物LASSBio-1140(3c)和LASSBio-1141(3e)作为镇痛和抗炎原型,它们能够减弱辣椒素诱导的热痛觉过敏(100μmol/ kg,
